New polls by Quinnipiac show a tightening race in several critical states, with Donald Trump now up one point in Ohio and tied in Florida. Trump has also cut into Hillary Clinton’s once double-digit leads in North Carolina and Pennsylvania.

A Quinnipiac University poll released June 30 shows a majority of voters believe all would-be gun buyers should be required to pass the same background check Orlando gunman Omar Mateen passed for his firearms.

The 2016 race for the Republican nomination has already challenged virtually every bit of political conventional wisdom. It would take an entire series of articles to detail how wildly wrong the pundit and commentariat class have been this campaign. The race has also been challenging for pollsters.

The latest Quinnipiac poll of Florida Republicans shows that Donald Trump is now leading that state with 44 percent of the vote, while home state Senator Marco Rubio is in second with only 28 percent. Ted Cruz is now in third place with 12 percent.
